Audience Scanning - Dancing with the stars

[sugeek]

about ~2:20ish

I was just wondering who did the show, the beams look fat enough and it was the non-public floor I am sure it should be legal just curious. I doubt it is the x-laser polaris but maybe it is the turn your laser into a moving mirror LED cannon optic from ant-eater corp. I would suspect slick rick's good friend who is great with varience's may have been of help...

It is 100% legal to hit people who are working, with any power of lasers, as long as they are given a run down on laser safety. Laser Fantasy shot a fan of 40Watt beams through Bill Gates...

Thanks Rick, I was sure it was legal but I always like you referencing you lovely lady LSO/Lawyer. The question still is who was hired for the show.

Rick, Adam,

Interesting - looks like all the beams terminated on the dance floor or the lower portion of the balcony.

Maybe in the US, but not in Western Australia !

The legislation does not discern performers any different to any other spectator...

"Its 100% legal to hit people who are working, with any power of lasers, as long as they are given a run down on laser safety."

For the avoidance of any doubt, that statement is wrong!

fwiw, I believe this show's werk is often, if-not all, done by 'Lightwave', and, they *have* approval to do audience and/or performer-scanning with certain-of thier systems (they got it added to thier Var for the 'floyd-prism' fx they did for Roger Waters' tour, in ~2007-8..) you can find it all up on Regulations.gov...

..as-to:

It is 100% legal to hit people who are working, with any power of lasers, as long as they are given a run down on laser safety.

...can you kindly 'school' us-all and quote the 'chapter and verse' as proof of this statement? Not what I understand is (still) the-case, so, if something's 'changed', please share!

Thx...

I saw this live and immediately wondered about it. I know it's legal to audience scan in the US and there are a few companies whose variance allows them to do that but, this one did surprise me. The one thing I noticed though was the beams hitting the dance floor and cast did look huge. I know there are some stipulations for actors/performers when it comes to three meter rules and things like that but, don't recall the exact parameters. It DID quickly catch my attention and start the brain churning when I saw the performance as to how they got away with it, as it smacks in the face everything we read and talk about here.

Frame by frame though, at about 2:42, the beams looks to be about the diameter of Cheryl Burkes thigh.

When I worked for the really big amusment company in the early 90's, the rule was you could get close but NOT hit the performers.
Provided you trained them, they wore custom made costume googles if needed and had things like safety switch pads, beam break sensors, etc.

In other words, there had to be independent hardware that killed the system output, if the human or system screwed up.
That equipment had to be manually reset in the event of a incident, not automated.

Ie 3 meter rule was waved under some circumstances, as long as you did ALARA measures and did nightly QC checks.

The Mouse supposedly had a system at e_cot where even the show techs stood on safety switch pads, in order to enable some special things to be done.
That would have to had QCed Software and Hardware.

You might have to have a two person safety check or things like that to do "Special" fixed install effects.

But at no time could we whack a performer with more then Class IIIA.

I've heard much of this has "Gone Away" in present practice, except for a few companies who have a track record of doing it right.

I used to have the details in writing some place, but I have lost that folder in a move.

If you want to see Jen Lopez panicking/angry, watch her music video of the KTP scanning around her legs, while she stands/dances on a brick wall or something.
Rumors in cheesy checkout line publications said she got nasty burns on the back her of legs. I dont read such things, but I saw the headlines. Doing that properly would have had her standing on a safety switch pad.


It constantly amuses me that if many PLers implemented real QC checklists and logs, they might be allowed to do some really neat things. However, we always must caution that if you do not have the financial/technical/brainwerks/guts and gumption means to do the ahead of time paperwork, measurements, and QC, then you should NOT be trying this. So its a catch 22. You cant do it if you dont learn how, and you can't learn how if you don't do the advanced thinking work.

"How can you have any pudding if you don't eat yer meat" --Floyd...

Of course if you have "PE" or "Chartered Engineer" on your name shingle and a engineering degree, its easier to get this approved. \

My supervisor at the "facility" had a PE and "The Stamp". Having the stamp on the documents and drawings means beaucoup lots to regulators. They can come after a PE in ways they can't hit a company.

No PE is going to risk his license allowing unsafe Shinnanigans. PEs can be contracted for those who want some "special" things worked on.
